SON, a citizen of the United States,-reSiding" at Boston, county of Suffolk, Statev off.

of which the following is a specification} reference being had therein to the 'accom panying drawings. i

The invention relates to a improvement in aerialtoys.

Possible ecol sistent with strength and figkh that when viewed from the same position one of the wings is upwardly in'clined while' edge which enables the wings to cut the air with less resistance than'if it were of-un1-' form thickness transversely. The crowned upper face also lessens the resistance of the air during the ascent of the device. The under face should be flat as it affords greatersustaining power to resist falling by gravity.

The spindle B is provided with means for rotating'it bymeans of 'a string or the like, as shown at 4. Preferably this string is detachably connected with the spindle somewhat above the middle of its length but this is not essential. The spindle is shown as provided with a transverse'hole lOthrough' which the end of the string is loosely threaded to keep the stringv from slipping during the winding and unwinding, the string then being wound about the spindle, as shown in Fig. 2. The outer end of the string is provided with suitable means for a finger hold. Preferably a short.

stick 5 is employed but any other suitable finger grip may be used. After one end of the string is threaded through the hole, it

being merely just passed through the hole,

the other part of the string is wound around the spindle as shown'in Figs. 2 and 3 preparatory to rotating the spindle to operate the device as already described, the winding being counter-clockwise.

A guide member is provided to support and guidethe string and to enable the operator to properly hold the device during the rotation. The preferred form of guide is a semi-tubular shell, as shown'at 6, the inner diameter of the guide being slightly larger than the diameter of the spindle so that the concave face will partially embrace the spindle and the coil of string, as shown in Figs. 2 and 3. v I p The guide 6 is formed with a thin slot 7 extending'froin one side edge of the guide transversely inward'for some distance, the slot being of a width to easily receive the string. The guide should be positioned on the spindle with the concave face of the guide embracing the spindle and coiled' string and with the slot engaving'the' un coiled portion of the string. The guide and the spindle may be grasped between the thumb and one of the fingers of the left handfas' shown in dotted lines, in. Fig.2. The pull handle 5 onthe outer end; of the string may be held by two of the fingers of the right hand, the string passing between the fingers, as shown in Fig. 2. The spindle spindle,

end.-

and guide member should be held lightly but steadily by the left hand so that the spindle may easily rotate when the string is 'pulled by the right hand and quickly unwound from the spindle thus furnishing "spindle, it will slip out again when the string is all unwound, leaving it free from the spindle. On account of the inclined faces of the wings, the rotation of the wings and of the spindle on the axis of the spindle will cause the spindle and the wings tofly' upward until the rotation of the spindle and wings slow down when the device will be gin to drop. If the spindle is held in a vertical position when ity is rotated,-it'-willbegin its ascent in a vertical direction. By holding'the spindle at a slight angle toothe vertical when it is rotated, the flightwill.

at first be'in' the same direction as the at which the spindle is headed; 1

Of course, the size and weight ofthe device andnumber of windings of the string and skill in manipulation will all effect the duration of the flight.

Instead of making the guide semi-tubular as described,'it may be made tubular, as shown at 8 in Figs. 7 and 8. In such case, it will be formed with a slot 9 extending transversely inward to receive-the string. When it is made tubular, the spindle will have to rise out of the guide member or the guide member will have to be pulled directly down in order to'release the spindle from the guide, whereas in the se1ni-tubu lar form previously described,- the guide member may be pulled away laterally.

The spindle being fast to'the top memangle 'ber, goes with it in its flight and stabilizes with the head and extending from the under face of the head at right angles thereto,

in combination with a separable guide memdinal groove throughout its length to receive the spindle, said guide being formed;

with a thin transverese slot extendingfrom ber having one side formed with a longitu-' one side edge of the guide inwardly to'in-i tersect said groove and adapted to releaseably engage a string wound around the said slot being open at its outer 2. Amman toy comprising a'liea d member having two oppositely extend ng wings,

a spindle connected with the head and extending at right angles thereto, in co1nbination with a separable, semi-tubular guide member having one side concave in transverse section throughout its length, the groove formed by the concave face being adapted to loosely receive the spindle in the axial direction thereof said guide being formed with a thin transverse slot extendingfrom one side edge inwardly to intersect said groove, a string having one end portion adapted to be wound around said spindle the other end being free While the intermediate portion engages said slot, the

inner end of the string being releasable from the spindle as soon as the string is unwound, said guide member being adapted to be held by the hand to maintain the string in the slot during the unwinding and, being at all times releasable at will from the spindle and from the string in a lateral direction, the winding of said string around a the spindle and its releasable engagement with said slot being the only connection 'between the spindle and the guide.

In testimony whereof I aflix my signature.
